External libraries scan not working properly

[JoostdeJonge123]

The bug

Hi,
I've Immich running as I want at the moment, but I'm running into an issue. I want to use my existing photo library via External Library, which is based on an external device.

When entering the path as //mnt/foto/2023 everything is working perfectly
When entering the past as //mnt/foto it is not scanning (jobs stay empty)

With CLI to //mnt/foto I can perfectly see all sub folders, also with all the files inside.

Any help is appreciated. (not sure if this is a bug)

Do you have a double forward slash in your path? I think it should be single forward slash i.e. /mnt/foto

[JoostdeJonge123]

Oops, typo in my bug report. I use "/mnt/foto" in Immich....

[JoostdeJonge123]

Looking into logfiles, I get the error "Error: ENOSPC: System limit for number of file watchers reached" that perhaps gives some ideas?

[alextran1502]

Yep, you will have to increase the number of max file watch on your system https://stackoverflow.com/questions/53930305/nodemon-error-system-limit-for-number-of-file-watchers-reached

[JoostdeJonge123]

(thanks for your quick replies)
What limit should I use, increasing to 131070 does not directly fix it...

[alextran1502]

Try this 524288

[JoostdeJonge123]

Yes, now it seems to be working, thanks!
